President Donald Trump marked the 250th anniversary of American independence with a speech that began by praising American exceptionalism. However, the tone shifted as he warned of a threat to American liberty.

The speech was delivered from Mount Rushmore, a national park honoring prominent US presidents. Trump's language was similar to his recent speeches, but the setting made it notable.

Further details about the speech and its context are available from KSAT 12, the local news source in San Antonio. Readers in Alamo Heights can refer to the source for more information about the president's address and its significance.
